Groundwater microcosms were treated with terbuthylazine at a concentration of 100 mg L1 and degradation of the herbicide was assessed. The bacterial community structure abundance and phylogenetic composition and function carbon production and cell viability were analysed. The bacterial community was able to degrade the terbuthylazine; in particular, Betaproteobacteria were involved in the herbicide biotransformation. Identification of some bacterial isolates by PCR amplification of the 16S rRNA gene revealed the presence of two Betaproteobacteria species able to degrade the herbicide Advenella incenata and Janthinobacterium lividum. PCR detection of the genes encoding s triazine degrading enzymes indicated the presence of the atzA and atzB enes in A. incenata and the atzB and atzC genes in J. lividum. The nucleotide sequences of the PCR fragments of the atz genes from these strains were 100% identical to the homologous genes of the Pseudomonas sp. strain ADP. In conclusion, the results show the potential for the use of a natural attenuation strategy in the treatment of aquifers polluted with the terbuthylazine. The two bacteria isolated could facilitate the implementation of effective bioremediation protocols, especially in the case of the significant amounts of herbicide that can be found in groundwater as a result of accidental spills. 71 Articolo pubblicato FEMSEC2010.pdf Articolo in rivista Elsevier 0168 6496 FEMS microbiology, ecology print FEMS microbiology, ecology print FEMS microbiol. ecol. print FEMS microbiology, ecology. print Federation of European Microbiological Societies microbiology, ecology print anna.barracaracciolo BARRA CARACCIOLO ANNA stefano.amalfitano AMALFITANO STEFANO paola.grenni GRENNI PAOLA TA.P04.005.007 Strumenti di mitigazione dello stress quali quantitativo per i sistemi idrici |
